Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32762 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- keydb (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n- redis (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n- valkey (Bitnami): affected from 5.0.0; fixed in 5.0.14, 6.0.16, 6.2.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-32762/ (Markdown: https://insights.sbomify.com/CVE-2021-32762/index.md)","id":"CVE-2021-32762","markdown":"https://insights.sbomify.com/CVE-2021-32762/index.md","name":"CVE-2021-32762","record":{"aliases":["ALPINE-CVE-2021-32762","AZL-61842","AZL-6851","BIT-keydb-2021-32762","BIT-redis-2021-32762","BIT-valkey-2021-32762","CLEANSTART-2026-EF94463","DEBIAN-CVE-2021-32762","GHSA-833w-8v3m-8wwr","UBUNTU-CVE-2021-32762"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Redis database","requires_auth":"low_privilege","summary":"Integer overflow in hiredis library used by redis-cli and redis-sentinel can lead to heap overflow and potential code execution on systems without allocator overflow checks.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"management_services_for_element_software","vendor":"netapp"},{"product":"management_services_for_netapp_hci","vendor":"netapp"},{"product":"communications_operations_monitor","vendor":"oracle"},{"product":"redis","vendor":"redis"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks. Most modern systems do and are therefore not likely to be affected. Furthermore, by default redis-sentinel uses the jemalloc allocator which is also not vulnerable. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow that can lead to heap overflow in redis-cli, redis-sentinel on some platforms","id":"CVE-2021-32762","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"debian:debian_linux","products":["debian:debian_linux","fedoraproject:fedora"],"type":"integer_overflow","year":"2021"},"n_packages":3,"n_references":9,"next":{"headline":"Regular Expression Denial of Service in OpenProject forum messages","id":"CVE-2021-32763"},"packages":[{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"keydb","purl":"pkg:bitnami/keydb","source":"BIT-keydb-2021-32762"},{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"redis","purl":"pkg:bitnami/redis","source":"BIT-redis-2021-32762"},{"ecosystem":"Bitnami","fixed":["5.0.14","6.0.16","6.2.6"],"introduced":["5.0.0","6.0.0","6.2.0"],"last_affected":[],"package":"valkey","purl":"pkg:bitnami/valkey","source":"BIT-valkey-2021-32762"}],"prev":{"headline":"Integer overflow issues with *BIT commands on 32-bit systems","id":"CVE-2021-32761"},"products":["redis"],"published":"2021-10-04","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["redis"]},"summary":"Integer overflow in hiredis library used by redis-cli and redis-sentinel can lead to heap overflow and potential code execution on systems without allocator overflow checks.","url":"https://insights.sbomify.com/CVE-2021-32762/"}
